WTA20SACJTB

Overview

The WTA20SACJTB is a rectangular MIL-DTL-55302 series board mount receptacle manufactured by Molex/AirBorn. It features a dual-row configuration with 20 positions and a 2.54 mm (0.100 inch) contact pitch. The unit utilizes gold-plated copper alloy socket contacts terminated via solder cups. Constructed with a polyphenylene sulfide (PPS) plastic body, it supports a rated current of 5 A and withstands up to 1 kV. The component operates within a temperature range of -65 °C to +125 °C and offers an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Utilizes gold-plated copper alloy socket contacts for corrosion resistance and stable conductivity
• Features a polyphenylene sulfide (PPS) housing providing thermal stability and mechanical strength
• Designed for vertical board mounting with solder cup termination for secure PCB integration

Applications

• Military and aerospace electronic systems requiring ruggedized connectors
• Avionics and flight control equipment interfaces
• Ground-based defense communication hardware
• High-density signal distribution in harsh environmental conditions

Procurement Notes

Verify the specific suffix codes against official AirBorn or Molex documentation to confirm exact contact type, orientation, and hardware configuration. Ensure compatibility with mating plugs regarding MIL-DTL-55302 standards. Confirm RoHS compliance status and material certifications prior to procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 20-position, dual-row MIL-spec receptacle is required for board-level applications. Consider the 2.54 mm pitch and solder cup termination method for PCB layout constraints. Evaluate the PPS housing material for thermal performance requirements exceeding standard plastics. Verify that the 5 A current rating and 1 kV voltage limit align with system electrical demands.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical environments. The series offers various contact counts and termination styles to support diverse military and industrial applications. The WTA20SACJTB specifically addresses needs for compact, high-density connections with robust mechanical and electrical performance standards defined by military regulations.

Replacement Considerations

Equivalent parts include those adhering to MIL-DTL-55302 with matching 20-position, dual-row, socket configurations. Verify dimensional compatibility and pinout alignment before substitution. Alternative suppliers may offer cross-referenced models, but strict adherence to military specifications is essential for functional interchangeability.
